Abstract

Chang (1976) found that up to 46% of the horizontal kinetic energy in the Strait of Georgia (GS), British Columbia, is contained in current oscillations possessing periods exceeding 4 days. In an attempt to explain these observations we present here a class of low-frequency oscillations in a model channel of GS. The Strait is modelled by an infinitely long, rectangular channel with a bottom that slopes upwards to the east; the stratification is idealized by a two-layer system. This model admits northward-travelling, topographic planetary waves with frequencies that lie in the observed range for reasonable values of the wavelength. However,the kinetic energy of these waves is mostly confined to the lower layer, in contrast to what is observed.
